BACKGROUND: The consumption of addictive substances is common in adolescence and raises concerns about future addiction. We investigated addictive substance consumption among young people to inform the design of drug intervention programmes.

METHODS: Participants were a population-based sample of 14- to 24-year-olds from Paredes, northern Portugal. A self-report questionnaire measured social and health variables, including tobacco, alcohol and illicit drug consumption. Results Data were analysed for 731 valid responses. Participants who had drunk alcohol did so first at 14.7 years (mean); 15.3% (95% confidence intervals [CI]: 12.9-18.1) drank alcohol regularly (more than 1/week, adjusted for age and sex) (95% CI: 12.9-18.1). Participants who had smoked tobacco did so first at 14.8 years (mean); 16.6% (95% CI: 14.0-19.5) were regular smokers. Illicit drug consumption was reported by 16.7% of participants (95% CI: 14.2-19.6) and 10.4% consumed drugs regularly.

CONCLUSION: We found a high prevalence of addictive substance consumption, particularly alcohol. As cultural attitudes likely influence alcohol consumption, a multigenerational approach is needed to address adolescent consumption. Participants' main sources of drug information were family members. Strategies are needed to promote drug literacy in parents and other relatives to change adolescents' culturally acquired habits of addictive substance consumption.
